IMPROVEMENT IN COMBINED SEEDER AND CULTIVATOR.

TheSchcdule referred to in these Letters Patent and making part of the saune.v

To all whom it may conce-rn Be it known that I, CLARK ALvoRD, of Westford, in the county of Dodge-,and State of Wisconsin, have invented a new and improved Combined Seeder and Cnltivator; and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation of the same, reference being had to the accompanying drawings, making a. part of this specilication, in which- Figure l is -a transverse vertical central section;

Figure 2, a plan view; and

Figure 3', a detached Ielevation of the grooved seederwheel. v

The rst part of this invention relates to a seeder; and consists cfa seeder-wheel, placed in front or rear, and, for the most; part, outside the seed-box, but eiltering partially within the same, and receiving in its circuxnterential V-shaped groove, a portion of the seed, which portion it carries under and out, and discharges over `the stop H, the circumferential groove being provided with transverse partitions, so constructed as to carry the seed before them until the proper moment, and then discharge it over the stop.

The second part of the invention relates to a en ltivaton; and consists in pivoting the front ends of the drag-bars to the front side of a frame, which frame is pivoted at its rear side to the axle, the latter. being of eccentric form, and capable of rotating in the wheels and in the frame, and operating, when rotated, to raise the drag-bars out of the ground, and bearing lingers, which, during such raising of the drag-bars, pass between ,them in an opposite direction, and the movement being continued, cleans the teeth; the tongue being also piroted, aty its rear extremity, in the saidframe, and the resultant of those contrarily-acting forces, the resistance of the cultivator-teeth, and the motive-power, being the elevation of the said frame, and the consequent cessation of its pressure, and of the seeder which rests yupon it, upon the horses necks.

A'is the seed-box, vresting on the frame B.

The inclined front side of the seed-box is vertically slotted, and in the slots are the rear portions of the seeder-wheels a, the main parts ot" said wheels being outside the seed-box.

The seeder-wheels have circumferential grooves, a', of V-shape, which readily receive the seed, and are provided with cross-partitions, af', which aid in propelling the seed, when in the grooves, out of the box, and to the end ofthe channel b, in which the wheel revolves.

Said cross-partitions extend unbroken across 'the groove, at the bottom, but not at the top, being each `composed of two, ridges, projecting fro'm'the sides of the groove, directly opposite each other, and not meeting at the top, but leaving a central interval, which allowsthe seed readily to fall ontof the groove, when arrived at the end of the channel.

The frame B is pivoted, at its rear side, upon the axle B', and toits upper front corner the forward ends of the drag-bars c are jointed.

Thetongne C is jointed, at its rear extremity, in the frame B, beneath the drag-bars. Hence, when the cnltivator-teeth are dragging in the ground, the front part of the frame B is elevated by the resultant of the two opposite forces, and the weight of such frame and of the seed-box taken otl the necks of the team.

The drag-bars c rest, when elevated, upon the edge of the eccentric'axle B.

The latter is provided with a handle-lever, B, by turning which downward, the eccentric axle is made to stand up edgewise, and raise the drag-bars out of the. earth. f v 1 At the same time, the fingers c', which project from the rear of the axle, parallel with the handle, pass between the drag-bars, and clean the teeth.

This cultivator is designed to be used, on occasion, for cleaning cotton-stalks from the field, at the same time that it cultivates.

Having thus described my invention,

Vhat I claim. as new, and desire to secure by LettersPatent, is-

l. The lseeder-wheels a, provided with V-shaped circumferential grooves, and centrally open cross-partitions et", as and to the 'end set forth.

2., Ihc eccentric axle B, combined with thepivoted drag-bars c, as und for the object specified.

3. The eccentric axle B', combined with the clean-- ing-lingers c', as and for the object specified.

4c. The eccentric axle B', combined with the cleaning-tingersc, and pivoted drag-bars c, as and for the purpose explained. e l

5. The pivoted frame B", combined with'the pivoted tongue C, and pivoted drag-bars c, in lthe `manner and to the end specified.

(i. The combination of a seeder with a cultivator when the drag-bars are located between the seedingbox and axle, substantially as and for the purpose set forth.
